Clearing Your Cache

What is a cache and why should it be cleared?

Many websites contain hundreds or thousands of files.  In order to keep the loading speed of these websites acceptable, a computer will save many of the components of the website locally.  A browser can then recall many of these components from it's memory which is easier and faster then grabbing it over the internet.  The problem with this is that when new components replace the remembered files, the new components will not appear.  The solution to this is to clear the cache to delete the old components so that it may remember the new components.
